The first official trailer for Marvel’s upcoming space adventure, “Guardians of the Galaxy,” is set to debut Tuesday night on “Jimmy Kimmel Live,” but impatient comic book fans can check out a 19-second teaser for the trailer, released Tuesday morning.

The film, due in theaters Aug. 1, is directed by James Gunn (“Super”) and based on the Marvel comic of the same name. Chris Pratt stars as the roguish anti-hero Peter Quill, a.k.a. Star-Lord, who steals a mysterious orb and consequently finds himself on the run from powerful villain Ronan (Lee Pace), whose evil plans threaten the universe. Quill is forced to team up with a ragtag squad of alien misfits to battle the cosmic threat.

It’s a quirky concept (one of the characters is a furry creature named Rocket Raccoon, voiced by Bradley Cooper), and early footage shown at Comic-Con International in San Diego last summer suggests the film adaptation will embrace the comic’s oddball elements with snark and humor.

The new teaser, however, seems to take a more serious tone, focusing on exploding spaceships and muscled bad guys. The teaser also offers a glimpse of Zoe Saldana, decked out in green as the assassin Gamora, Dave Bautista as Drax the Destroyer, “Doctor Who” star Karen Gillan as Nebula (with a bald, blue head), and the tree-like humanoid Groot, voiced by Vin Diesel. Check it out in the video below.

The film also stars Michael Rooker as Yondu, Djimon Hounsou as Korath, Benicio del Toro as the Collector, Glenn Close as Nova Prime Rael and John C. Reilly as Rhomann Dey.

Pratt will introduce the full trailer Tuesday night on “Jimmy Kimmel Live.”
